176 MANUAL OF PHILIPPINE BIRDS. 
“The young bird is browner than the adults, with white mesial streaks 
on the wing-coverts; crown of @#@4d dusky black; under surface of body 
less gray and washed with brown.” (Sharpe.) 
“Extremely common. Found both along the seashore and about fresh- 
water streams and lakes.” (Bourns and Worcester MS.) 
146. BUTORIDES AMURENSIS (Schrenck). 
AMUR GREEN HERON. 
Ardea virescens var. amurensis SCHRENCK, Reis. Amur]. (1860), 1, 437. 
Butorides amurensis SHARPE, Cat. Birds Brit. Mus. (1898), 26, 181; Hand- 
List (1899), 1, 200; McGrEcor and Worcester, Hand-List (1906),

Calayan (McGregor); Cebu (Hverett, McGregor); Luzon (Whitehead); Pa- 
lawan (Everett) ; Samar (Steere). Greater Sunda Islands, China, Japan, Celebes, 
Amurland. 
Although in color this species seems to be exactly like B. javanica it is 
much larger; the length of wing is particularly noticeable and the bill 
is longer, and deeper. A male collected by Major Mearns measures: 
Wing, 210; tail, 73; culmen from frontal feathers, 66; depth of bill at 
posterior border of nostril, 15; tarsus, 54; middle toe with claw, 62. 
A female from Calayan measures: Wing, 197; tail, 69; culmen from 
frontal feathers, 64; depth of bill at posterior border of nostril, 13 ; tarsus, 
52; middle toe with claw, 54. 
Some of the records for B. javanica probably refer to the present species 
but it is impossible to disentangle them. 
147. BUTORIDES SPODIOGASTER Sharpe. 
NICOBAR GREEN HERON. 
Butorides spodiogaster SHARPE, Bull. Brit. Orn. Club (1894), 3, 17; Cat. 
Birds Brit. Mus. (1898), 26, 182, pl. 2; Hand-List (1899), 1, 200;

Palawan (Mearns). Andaman and Nicobar Islands. 
“Adult.—Similar to B. javanica, but darker gray on the under surface, 
which is of a sooty-slate color with a slight tinge of rusty on the abdomen, 
cheeks and ear-coverts uniform slate-color. It much resembles B. stag- 
natilis, especially the birds from Flores, but it is not so dingy under- 
neath and has a less shade of rusty on the abdomen. ‘Bill black, lower 
portion of lower mandible, from base to tip, edged pale horny; front 
of tarsus, toes, and claws brownish green, bare portion of tibia and back 
of tarsus dirty greenish yellow; naked skin round eye dull green, tinged 
with yellow in front; eyelids deep green. (Hume.) Length, 445; 
culmen, 60; wing, 193; tail, 53; tarsus, 43.” (Sharpe.) 
This species differs from both B. javanica and amurensis in its much 
darker color, particularly of the under parts which are nearly uniform
